"First off the product arrived very quick especially considering I ordered it right before the memorial Holiday it only took 3 business days.I spent under 2 hours putting it in with the help of a buddy and drove it right after with no problems. The car belongs to my daughter who cannot tell the difference but i was not expecting her to. I did hear a difference in sound eventhough the car is a V6 and I could tell performance was enhanced.This is the 2nd CAI i have purchased by K&N but the first from autoanything and the price was great and service was just as good." —Ascanio T from Macomb, MI bought a K&N 69 Series Typhoon Intake Systems for a 2011 GMC Terrain.
